Under California’s primary system, the top two candidates regardless of political affiliation move on to the general election, leading to cases in which candidates will be facing members of their own party this November.

4th Congressional District — Three-term incumbent Tom McClintock, one of the state’s most recognized conservatives, will be running against GOP candidate Art Moore, an Iraq War veteran seeking office for the first time. McClintock gained 56 percent of the vote in the primary. Moore picked up about 23 percent, but conditions should be more favorable for him in the general.

17th District — Seven-term incumbent Mike Honda faces a challenger with strong backing from Silicon Valley, lawyer Ro Khanna. Honda gained 48 percent of the vote in a four-candidate primary. Khanna finished in second with 28 percent. Despite swearing off any money from political action committees, Khanna had raised more money than Honda leading up to the primary.

19th District — No Republican candidate ran in this strongly Democratic district. Ten-term incumbent Zoe Lofgren will be a huge favorite against fellow Democrat Robert Murray. Murray ran as a Republican in 2012.

25th District — Even though Democrats had designs on challenging for the seat of retiring Rep. Buck McKeon, Republicans emerged as the top two vote-getters. Former state legislator Tony Strickland picked up 29.6 percent of the vote in the primary, while state Sen. Steve Knight was a close second with 28.4 percent.

34th District — Another heavily Democratic district, and incumbent Xavier Becerra is expected to emerge victorious. He gained nearly 74 percent of the vote in June, and his next closest competitor, Democrat Adrienne Nicole Edwards, had just 14.5 percent.

35th District — In the race to replace Gloria Negrete McLeod, a first-term lawmaker who decided to come back home and run for county office, Democrat Norma Torres finished with 67 percent of the primary vote and Christina Gagnier had 15 percent.

40th District — Rep. Lucille Roybal-Allard, now serving her 11th term, is favored to defeat fellow Democrat David Sanchez, who seeks to cut defense spending.
